Analysis of the Zero Overvoltage Switching Phenomenon
IEEE Access, 2022 In common understanding, the fast switching speed of wide-bandgap devices leads to high overvoltage and oscillations, if no countermeasures are taken. Those countermeasures were introduced in the past, and include methods such as build-in gate resistors ...

A comprehensive design approach for a three‐winding planar transformer
IET Power Electronics, 2022 In this paper, a new three‐winding planar transformer design with the integrated leakage inductor is proposed for a triple‐active‐bridge converter. It enables two output voltage levels: a high voltage (HV) output port and a low voltage (LV) output port ...

Parasitic capacitance cancellation in filter inductors [PDF]
2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004 This paper introduces a technique for improving the high-frequency performance of filter inductors and common-mode chokes by cancelling out the effects of parasitic capacitance. This technique uses additional passive components to inject a compensation current that cancels the parasitic current, thereby improving high-frequency filtering performance ...
